Modular furniture system

ABSTRACT

A modular furniture system having a small set of interchangeable base components which can be assembled using common tools and disassembled without damaging the components, allowing the consumer to disassemble and reassemble the components to form another piece of furniture. The modular furniture system has a plurality of structural members, each with multiple rows of openings which extend through the structural members. A first row of openings of the multiple rows of openings has equally spaced first openings having a first diameter. A second row of openings of the multiple rows of openings has equally spaced second openings having a second diameter which is different than the first diameter. A first center line extending through the center of the first openings of the first row of openings is parallel to a second center line extending through the center of the second openings of the second row of openings.

FIELD OF THE INVENTION

The present invention relates to a modular furniture system which utilizes structural members with pre-manufactured holes and various connectors to construct a wide variety of furniture pieces for different functional uses.

BACKGROUND OF THE INVENTION

The term “modular furniture” is generally used today to encompass all furniture that is designed or composed of standardized units or dimensions in order to allow for easy assembly and repair or flexible arrangement. It is most commonly used when referring to modular seating systems such as sectional sofas which can be arranged into numerous seating configurations, or modular storage systems such as modular cabinets which can be arranged into numerous storage configurations. These modular systems work well but are generally designed and intended to serve only one functional use. A sectional sofa for example, while allowing for numerous seating configurations, would not serve well as a storage solution.

A modular furniture system on the other hand is a system that is designed to construct multiple furniture pieces using the same base components and which can serve multiple functional uses.

There are a number of known examples of modular furniture systems which have been designed to serve multiple functional uses by creating different furniture pieces however they generally suffer from one or more of the following drawbacks. The systems require special tools or skill sets to assemble or reconfigure into different furniture pieces. Some components of the system are too specific to one functional use and can't be reused to build other furniture pieces for other functional uses. The systems serve only a few functional uses well and become awkward if forced or stretched to serve other functional uses.

For example, U.S. Pat. No. 5,802,780 to Hammerschlag discloses a construction system with pre-manufactured rows of holes for fastening. This system builds off of U.S. Pat. No. 4,620,747 to Lemmon which discloses a custom construction system which utilizes basic construction components to produce a wide variety of furniture and home improvement projects. Both systems are designed more for the home DIY carpenters and require structural members be cut or modified to build certain furniture pieces. This limits the potential users who would purchase such a system and also limits the potential for reuse since structural members which may have been cut or modified to build one piece of furniture might not work for another piece of furniture. These systems also both have structural issues and either require additional structural members to shore up the main structural members which adds additional cost or require special hardware to reinforce which damages the structural members and limits the potential for reuse.

U.S. Pat. No. 6,783,182 B1 to Gallagher discloses a modular furniture system comprised of legs, seat frames, back frames and arm rests which can be assembled and connected in various configurations to form numerous seating arrangements. While this system may allow for numerous seating arrangements, some components of the system are too specific to one functional use and cannot be reused to build other furniture pieces such as tables or bookshelves. Similarly, U.S. Pat. No. 8,733,851 to Lee discloses a modular furniture system comprised of surface members, junctions and connectors which can be assembled and connected in various configurations to build numerous storage solutions such as shelves, cabinets, stands and desks. However, the components of the system and the method of assembly limit the usage of the system to storage, and it cannot be used to build other furniture pieces such as chairs.

U.S. Pat. No. 9,078,515 to Keragala discloses a modular interior design system comprised of members that are joined together to form modular cells. These modular cells, which resemble cubes or boxes, can then be combined with other modular cells to form furniture pieces. The system is similar to U.S. Pat. No. 8,573,716 to Zalewski which discloses a storage shell that includes a plurality of sidewalls to collectively define a chamber therebetween. While these systems may work well for some functional uses, they veer away from what one would consider conventional furniture design due to the cube like modular cells. Characteristics common to chairs and tables such as legs cannot be formed since the systems require members be joined together into modular cells. While the Keragala system can be “stretched” to construct a chair as shown in FIG. 31 of the patent, it strays from what one would consider a conventional chair with four legs and the system is better suited for other functional uses.

A final issue encountered with many known modular furniture systems is the durability of the components which make up the system. When assembled and disassembled multiple times, the components can break down and become damaged. This can cause multiple issues such as the loss of structural integrity, the components no longer connecting properly or securely, or the damage to the component is so extensive that it can no longer be used at all.

What is desired, therefore, is a modular furniture system that requires no special skills to modify and can be easily assembled and disassembled using basic tools. A modular furniture system comprised of base components that are not specific to one functional use. A modular furniture system that can build a wide variety of furniture pieces that serve multiple functional uses. A modular furniture system that is made of quality materials and will not break down after assembling and disassembling multiple times. A modular furniture system that can be extended using advanced components such as hinges, handles, and cushions. A modular furniture system that can personalized with an assortment of materials and colors.

Moreover, the features and benefits of the invention are illustrated by reference to the preferred embodiments. Accordingly, the invention expressly should not be limited to such preferred embodiments illustrating some possible non-limiting combination of features that may exist alone or in other combinations of features, the scope of the invention being defined by the claims appended hereto.

The embodiments are directed to a modular furniture system 10 which includes a small set of interchangeable base components which can be assembled using common tools and disassembled without damaging the components, allowing the consumer to disassemble and reassemble the components to form different pieces of furniture such as, but not limited to, the Adirondack chair 100 shown in FIG. 1, the side table 200 shown in FIG. 10, the bench 300 shown in FIG. 11, and the bookshelf 400 shown in FIG. 12. Referring to FIGS. 2 through 5, the modular furniture system 10 includes structural segments, elements or members 20, brackets 50 and fastening members 70.

As best shown in FIG. 2, the structural members 20 each have the same the same width W and depth D. However, various structural members 20 are provided in different lengths L. For example, in one illustrative system, the structural members may have a width W of 10 cm and a length L of between 10 cm and 100 cm (increasing in 10 cm increments). The depth D is dependent upon the type of material used to construct the structural members 20. This allows the structural members 20 to be assembled to form different pieces of furniture using the same structural elements 20 in a different pattern or configuration. For example, in FIG. 11, the bench 300 has different length structural members 20 which form the width, height and length of the bench.

As shown in FIG. 2, the structural members 20 have a generally planar first surface 22 and an oppositely facing generally planar second surface 24. The depth D of each of the plurality of structural members 20 extends between the first surface 22 and the second surface 24. A first end 26 and a second end 28 extends between the first surface 22 and the second surface 24. First side 30 and second side 32 also extend between the first surface 22 and the second surface 24. The edges provided between the surfaces, ends and sides are rounded to eliminate sharp edges.

The structural members 20 may be made from any material having the required strength characteristics required to support the load which the furniture is designed to hold. Such material includes, but is not limited to, hardwoods, furniture grade plywood, metal and injection molded plastic. Additionally, in various illustrative embodiments, materials or veneers, such as, but not limited to, high pressure laminate material, may be applied to the surfaces or faces of the structural members 20 to allow for various colors or textures to be used.

Multiple rows of openings are provided on each of the plurality of structural members 20. In the illustrative embodiment shown, each structural members 20 includes: a first row 34 of openings which has equally spaced first openings 36 having a first diameter d1; a second row 38 of openings having equally spaced second openings 40 having a second diameter d2; and a third row 42 of openings having equally spaced third openings 44 having a third diameter d3. A first center line C1 extends through the center of the first openings 36 of the first row 34 of openings. A second center line C2 extends through the center of the second openings 40 of the second row 38 of openings. A third center line C3 extends through the center of the third openings 44 of the third row 42 of openings.

The first center line C1 is essentially parallel to the second center line C2. The first center line C1 is essentially parallel to the third center line C3. The second center line C2 is essentially parallel to the third center line C3. In the illustrative embodiment shown, the first center line C1, the second center line C2 and the third center line C3 are essentially parallel to the first side 30 and second side 32 of the structural member 20. In the illustrative embodiment shown, the first center line C1, the second center line C2 and the third center line C3 are essentially perpendicular to the first end 26 and the second end 28 of the structural member 20.

As shown in FIG. 2, the third diameter d3 of the third openings 44 of the third row 42 is the same as the first diameter d1 of the first openings 36 of the first row 34. The second diameter d2 of the second openings 40 of the second row 38 is different than the first diameter d1 of the first openings 36 and the third diameter d3 of the third openings 44. In the embodiment shown, the second diameter d2 of the second openings 40 is larger than the first diameter d1 of the first openings 36 of the first row 34 and the third diameter d3 of third openings 44 of the third row 42, although other configurations may be used. For example, the diameter d2 may be twice the diameter d1.

The third openings 44 of the third row 42 are positioned in-line with the first openings 36 of the first row 34 along the length L of the structural members 20. The second openings 40 of the second row 38 are offset from the first openings 36 and the third openings 44 along the length L of the structural members 20.

The first openings 36 of the first row 34 and the third openings 44 of the third row 42 are equally spaced. The second openings 40 of the second row 38, while offset from the first openings 36 and third opening 44, are also equally spaced and are spaced apart the same distance as the first openings 36 and the third openings 44. However, other spacing of the openings may be used.

All of the openings 36, 40, 44 have a tapered lead-in surface extending from the first surface 22 and the second surface 24. The lead-in surface is dimensioned to receive the heads of the fastening members 70, thereby allowing the heads to be mounted flush with the first surface 22 and the second surface 24.

The hole patterns of the structural members 20 as described are designed to allow for the members 20 to be joined together in various combinations and patterns to form different furniture pieces.

Referring to FIG. 3, an illustrative bracket 50 is shown. Each bracket 50 has a first leg 52 and a second leg 54. In the embodiment shown, the first leg 52 is longer than the second leg 54 and is essentially perpendicular to the second leg 54.

The first legs 52 have a generally planar first surface 56 and an oppositely facing generally planar second surface 58. The depth D of each of the plurality of first legs 52 extends between the first surface 56 and the second surface 58. Sides 60 extend between the first surface 56 and the second surface 58. The edges provided between the first surface surfaces 56 and sides 60 are rounded to eliminate sharp edges. However, the edges provided between the second surface surfaces 58, and sides 60 are not rounded to provide better stability when provided in contact with the structural members 20.

The second legs 54 have a generally planar first surface 62 and an oppositely facing generally planar second surface 64. The depth D of each of the plurality of second legs 54 extends between the first surface 62 and the second surface 64. Sides 66 extend between the first surface 62 and the second surface 64. The edges provided between the first surface surfaces 62, and sides 66 are rounded to eliminate sharp edges. However, the edges provided between the second surface surfaces 64, and sides 66 are not rounded to provide better stability when provided in contact with the structural members 20.

The brackets 50 may be made from any material having the required strength characteristics required to support the load which the furniture is designed to hold. Such material includes, but is not limited to, aluminum, zinc, metal alloys, and plastic.

Openings 68 are provided on each of the brackets 50. The openings 68 provided on the first legs 52 are essentially identical to the openings 68 provided on the second legs 54. In the illustrative embodiment shown, the diameter d4 of the openings 68 is essentially the same as the diameters d1 of the first openings 36 and d3 of the third openings 44 of the structural members 20. All of the openings 68 have a tapered lead-in surface extending from the first surface 56, 62. The lead-in surface is dimensioned to receive the heads of the fastening members 70, thereby allowing the heads to be mounted flush with the first surface 56, 62.

As shown in FIG. 4, bracket 50 may include more than one opening 68 in the first legs 52 or the second legs 54. In such embodiments, the openings 68 are spaced apart the same distance as the first and third openings 36, 44, thereby allowing the openings 68 of the brackets 50 to align with the first and third openings 36, 44 of the structural member 20 to allow for proper assembly of the furniture

Fastening members 70 are best shown in FIG. 5. The fastening members 70 in the illustrative embodiment shown are sex bolts. Each fastening member 70 has a female internally threaded barrel 72 and a male externally threaded screw 74. Both the barrel 72 and screw 74 have heads 76. The heads 76 are configured to be received in the tapered lead-in surfaces of the openings 36, 40, 44, 68 such that the heads 76 are flush with respective surfaces when fully tightened. The heads 76 are designed to clamp or bind the structural members 20 and/or brackets 50 between the head 76 of the barrel 72 and the head 76 of the screw 74. As shown in FIG. 5, the fastening members 70 may have different lengths and diameters depending upon the requirement for assembly. The fastening members 70 may be made from any material having the required strength characteristics required to support the load which the furniture is designed to hold. Such material includes, but is not limited to, aluminum, titanium, metal alloys and plastic. While the fastening members 70 are shown as sex bolts, other type of fasteners can be used.

As shown in FIG. 13, accessories 80 may be provided to cooperate with the support members 20. In the embodiment shown, a silicon cushion 80 is shown with projections 82 which are dimensioned to be received in openings 40 to provide a frictional fit therebetween. However other types of projections and other methods of securing the accessories can be used. While a cushion is shown, other types or accessories, such as, but not limited to, lights, cup holders and glass tops, can be incorporated into the modular furniture system 10. In addition, other components, such as, but not limited to, hinges and handles may also be included in the modular furniture system 10.

During assembly, the structural members 20 are positioned and secured with fastening member 70 or with brackets 50 and fastening members 70. The structural members 20 can be positioned at different angles and different locations relative to each other to form the a multitude of items or furniture pieces, such as, but not limited to the chair, table, bench and bookshelf shown in FIGS. 1, 10, 11 and 12 respectively.

In order to assemble the various pieces of furniture, the structural members 20 must be joined or secured in different ways to ensure that the furniture is stable and can support the required load. FIG. 6 depicts one illustrative method of securing two support members 20 together. The support members 20 are joined at a ninety degree angle. In this position, respective openings 36, 44 of a first support member 20 align with respective openings 36, 44 of a second support member 20. Fastening members 70 are inserted through the openings 36, 44 and are tightened to secure the support members 20. As four fastening members 70 are used, the first support member 20 is fixedly secured to the second support member 20 in this position.

The fastening members 70 are tightened to fixedly secure the support members 20. In the embodiment shown, the horizontal structural member 20 is resting solely on the bracket 50 and all of the weight resting on the horizontal structural member would be transferred to the bracket 50 and fastening member 70. In an alternate configuration, the bracket 50 can be flipped so that the horizontal structural member 20 is resting on both the bracket 50 and the vertical structural member 20.

In another alternate embodiments, a bracket 50 having two opening 68 on either leg 52, 54 can be used. The operation of this bracket 50 is the same, except that the openings 68 on each leg 52, 54 would align with respective openings 36, 44 of each support member 20. Fastening members 70 would then be inserted and tightened in all of the respective openings.

FIG. 9 depicts another illustrative method of securing three or more support members 20 together. The support members 20 are joined at a ninety degree angle. In this position, respective openings 36, 44 of a first support member 20 align with respective openings 36, 44 of a second support member 20. Fastening members 70 are inserted through two of the openings 36, 44 and are tightened to secure the first and second support members 20. The third support member 20 is joined at a ninety degree angle to the second support member 20 using a bracket 50. In this position, a respective opening 36 of the second support member 20 aligns with a respective opening 68 of the bracket 50 and a respective opening 36 of the third support member 20 aligns with another respective opening 68 of the bracket 50. A fastening member 70 is inserted through each of the respective opening 36 of the second support member 20 and the respective opening 68 of the bracket 50 and the respective opening 36 of the third support member 20 and the other respective opening 68 of the bracket 50.
